I know what you mean.
In my opinion, RTS games like the starcraft or age of empires series are more comprehensible to a non-player. You can visually see the armies and bases and have a sense for what's going on. there isn't information that's obscure to the viewer like items and cooldowns in a moba
the pace is also slower than in fighting games, and interactions have more planning, which allows viewers to anticipate big moves, ambushes, tricky plays, etc
You did indeed stab me in the back. However, you are only level one, whilst I am level 50. That means I should remain uninjured.
